Was mark Antony in love with Cleopatra?

No, forget about the love aspect of the relationship between Antony and Cleopatra. Both of them were sel-centered persons and both of them had their own agendas. They used each other. Cleo used Antony to keep her country's independence (at least for a while) and to add more territory to Egypt. Antony used Cleopatra for the money to finance his military ventures. They liked each other and they were in agreement as to their politics. That is why they formed their political alliance.
